just wondering if anyone else has large animal bones in their tanks as a decoration. i have half a doe skull and a scapula in my 60 tall it looks pretty good and the loaches love them.
I would be worried about decomposition in places where the meat might still be intact. How old are these bones? How were they cleaned? How long have you had them in your tank? etc.....
you can seal them to make it work better. I don't have any in my tanks, but I do have over 200 skulls and skeletons that I have personally cleaned off.
i can get pics. but as for cleaning it was originally natural coyotes, racoons, beetles ect. then i boiled them but theres no meat left and as for marrow none in the skull and its a scapula not much marrow to be had.
i would like to see pics of this tank. also i was in the market for a skull for my RBP tank ( i opted out of it though) and you can find some really nice replicas if you are willing to pay the price. But as far as real bones go I don't think i would put any in my tank unless i sealed them first
I use cow bones (purchased at LFS for dogs) as a calcium source for my snails. As long as they are clean, and aged they are great decorations/calcium adders.
In water that is acidic, the bones will decompose rapidly to buffer the water. Be sure you're maintaining species that can tolerate the changes in chemistry that will occur after every water change. In alkaline tanks, the bones will last much longer.
Sealing bones in epoxy will render them stable for use in aquaria and will not affect the tanks parameters.
